Calculation of the gear ratio “i”
Calculation of the gear ratio “i”
Example:
   
 6th gearWheel drive shaft
Drive pinionZG1 = 42ZA1 = 22
Driven pinionZG2 = 31ZA2 = 69

i = Z2 : Z1 → Note
iG = Gear ratio = ZG 2 : ZG1 = 31 : 42 = 0,738
iA = Final group gear ratio = ZA 2 : ZA 1 = 69 : 22 = 3,136
itotal = Total gear ratio = iG x iA = 0.738 x 3.6 = 2.315
1)  Z1 = Number of teeth of drive pinion, Z2 = number of teeth of driven pinion
